Kua tāruatia ki te papatopenga
-\left(8x-1\right)+45=-285
Whakareatia ngā taha e rua o te whārite ki te 3.
-8x-\left(-1\right)+45=-285
Hei kimi i te tauaro o 8x-1, kimihia te tauaro o ia taurangi.
-8x+1+45=-285
Ko te tauaro o -1 ko 1.
-8x+46=-285
Tāpirihia te 1 ki te 45, ka 46.
-8x=-285-46
Tangohia te 46 mai i ngā taha e rua.
-8x=-331
Tangohia te 46 i te -285, ka -331.
x=\frac{-331}{-8}
Whakawehea ngā taha e rua ki te -8.
x=\frac{331}{8}
Ka taea te hautanga \frac{-331}{-8} te whakamāmā ki te \frac{331}{8} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
